I installed kittyporter so the cats could transport themselves to and from the catio. All the kitties but Guildenstern started using the kittyporter to move back and forth between the catio and the house soon after I installed it. It took Guildenstern almost a year before he would use the kittyporter without hesitation. He was afraid it might send him to dev null and be stuck in a cyber purgatory forever.

Be careful, Mr Bowie, it might be a trap………door. If you are going to experiment make sure the port is a good fit. Nothing worse than getting stuck in portals or with portions of you in parallel universes.
